Back-end developper

A couple of bugs and a development:

We have two bugs in the back-end, one that crashes the app (mobile and web) for certain users right after login, w had the case but it was confirmed during apple review process when they used a login that was older than 1 month and the app crashed. The other bug is about online payment, can't manage to pay the online subscription, neither with paypal or braintree, and it used to work ok...

The development is about connecting caracal to other services like withings, iHealth or Omron using their API, which are open and documented, so we could ask our users to connect with their withings, iHealth account to download their data in caracal. Need to be implemented wih all security and authorizations required for the management of personal health data.

Backend : PHP5, Zend Framework 2 + Doctrine ODM (MongoDb)
Frontend web: good knowledge of HTML/Javascript + Angular
Mobile: Xamarin/C#
